Our **Miles Per Galon (MPG) converter** allows you to switch between **units **used in fuel **efficiency **conversions **fast **and **effortlessly**. A **fuel-efficient automobile** uses little **gasoline **per 100 kilometers yet can drive a long distance on a single **gallon**. This **MPG converter **might come in handy when ordering an automobile from another country. If you’re going to a nation with different fuel efficiency units, be sure you bring it with you because the changes are considerable.

## What is MPG?

Whether you’re buying a **car secondhand **or **new**, you’ll want to know how many **miles per gallon** your new (or new-to-you) **vehicle **gets. Know what **MPG **stands for ahead of time, as well as all you need to know about **fuel economy **and your gasoline consumption, so you can purchase with confidence. MPG, or miles per gallon, is the distance an automobile can drive per gallon of gasoline, measured in **miles**. MPG is also the most common way of calculating a car’s fuel efficiency: Its MPG indicates how fuel-efficient it is.

The MPG of an automobile might be unpredictable due to various circumstances, making it difficult to obtain an exact **measurement**. For example, in every given situation, factors like traffic and road conditions might impact MPG. That’s why the **EPA **(**Environmental Protection Agency**) conducts testing on a set of standard courses before averaging the results to get a vehicle’s official MPG.

According to **All Car Leasing**, the EPA assigns each car three separate MPG ratings:

- Highway MPG is the average mileage a car gets while travelling on a straight road with no stops or starts, usually at a higher speed.
- City MPG: the average MPG a car will obtain in city circumstances, with slower stopping and starting.
- Also known as combined MPG, this is the average of highway and city MPG.

MPG is a vital measure to understand any car you’re thinking about buying. It informs you about the cost differences between operating different automobiles by estimating how much money you’ll spend on gas.

## Fuel economy conversions

The link between the distance a vehicle goes and the **quantity **of gasoline it uses is **fuel efficiency**. When calculating it’s vital to distinguish between the US and imperial gallon since they reflect different values. US gallons are mostly utilized in the **United States**, although they are also used in the several **Caribbean **and** Latin American nations**. An imperial gallon is used in **Commonwealth nations**, including the **United Kingdom** and **Canada**. Almost everywhere else on the earth, liters per 100 kilometers are utilized.

Another significant distinction is the measuring systems: when using miles per gallon (either metric or the US), the greater the figure, the more fuel-efficient the vehicle. Those who use liters per 100 km, on the other hand, normally aspire for a lower score because it means reduced gas expenditures. For example, 1 liter equals 235.2 US MPG or 282.5 Imperial MPG per 100 kilometers. Similarly, 1 US MPG is equivalent to 235.2 gallons per 100 kg.

## How to Convert Miles per Gallon (US) to l/100km?

To convert mpg to litres per 100 kilometers, first convert the gallon (US) to litres and then the miles to kilometers.

Conversion factor for kilometers to miles:

**1 mile = 1.609344 kilometers**

Conversion factor from US gallon to litre:

**1 US gallon = 3.78541178 litres**

Mpg (miles per gallon) in fuel consumption units:

*mpg = miles / gal*

We need to calculate litres per 100 kilometers, therefore multiply and divide the right-hand side by 100.

## How to calculate miles per gallon?

Calculate the fuel efficiency of cars in either the US or **metric values**. Calculate vehicle fuel efficiency in mpg US, mpg Imp (miles per Imperial gallon), km/l (kilometers per liter), or l/100km (liters per 100 kilometers) (liters per 100 kilometers). All units, mpg US, mpg Imp, km/l, and l/100km, are converted and displayed as equivalent fuel economy/efficiency ratings.

**mpg**= miles per gallon**US mpg**= miles per United States gallon**mpg Imp**= miles per Imperial gallon**km/l**= kilometers per liter**l/100km**= liters per 100 kilometers

You compute fuel efficiency in terms of distance per unit volume or distance/volume when you calculate miles per gallon (mpg) or kilometers per liter (**km/l**). The following outline applies to both computations in general. You compute volume per 100 units of distance when you calculate liters per 100 kilometers (**l/100km**).

*Miles driven ÷ gallons used = miles per gallon = mpg*

*Kilometers driven ÷ liters used = kilometers per liter = km/l*
